Instruction Exam 2 Chapter 6 part 2 Warmup 3 Janie is taking an exam in her history class On the exam a question asks her to state and discuss the five major causes of the Trans Caspian War Janie remembers four of them She knows there is a fifth but time is up As Janie is walking down the stairs all of a sudden she remembers that fifth point but it is too late Janie had a problem with A encoding B storage C retrieval pulling info back out of memory D evaluation 7 Which memory system provides us with a brief representation of all the stimuli present at a particular moment A primary memory B sensory memory briefest of all the memory stages proposed by the information processing model Visual sensory memory lasts only about one half a second C long term memory D short term memory 16 As you are skating down the street on your skateboard you think back to the day you accidentally skated into a parked car and had to go the hospital to get stitches The memory of this event would be described as a n memory A procedural B implicit C episodic D semantic memories rehearsed during sleep as well as during waking are more likely to be consolidated one can t learn something new while sleeping but new information can be better consolidated while sleeping sleep deprivation severely interferes with hippocampal function and memory SI Leader Ashleigh Ledet alede12 tigers lsu edu

retrieval What does it do improves aides memory Better at producing retrieval than massed practice Distributed practice is spacing study sessions Brain remmebers things in short bursts How would you go about this process Make an image in your mind encode it maintence rehersal Why is sleep important Memory formation Exercise blood flow to brain Mnemonics Distrubuted practice Imagery Sleep and Exercise Activity 2 Forgetting Forgetting Poor encoding storage decay retrieval failure Encoding Failure Retrieval Failure Storage Decay Inference Do you know what a penny looks like Nobody takes the time to encode the details of a penny TOT problem going from LTM back to STM leads to forgetting Memory Trace Theory physical change when memory is formed Decay memory loss b c time passes and emory trace isnt used Disuse memories not used will decay disappear Proactive old interferes with learning new and Retroactive new info interferes with retrieving old Mnemonics Distrubuted practice

3 Forgetting part 2 Reasons for Forgetting Encoding Failure Decay or Disuse Proactive Interference The information is not attended to and fails to be encoded Information that is not accessed decays from the storage system over time Older information already in memory interferes with the retrieval of new information Retroactive interference Newer information interferes with the retrieval of older information Using this assign each of these terms to a scenario 1 Ashleigh studied Italian all throughout high school and then studies French in college She goes to Italy and tries to speak Italian but realizes she can only remember French This is RETROACTIVE INTERFERENCE New interferes with old 2 While Ashleigh is studying abroad in Italy she decides to go driving through the country side She grew up in the US where she learned to drive and has a hard time adjusting to driving on the roads of Italy This is Proactive interference old interferes with new 3 Maggie has cycling class at 7 30 Last night she pulled an all nighter and was still half asleep when she parked her bike on one of the bike racks on campus Later that afternoon she has no idea where she parked her bike This is an example of encoding failure 4 After class Laura spoke to her teacher and set up a meeting time to go over her last psychology test though Laura was paying attention when talking to her professor she didn t get a chance to write it down When she opened her agenda later to write the meeting down she realized she couldn t remember it This is an example of Decay or Disuse Activity 4 Amnesia Situation 1 Danny got into a horrible car accident and suffered severe brain trauma He wakes up in the hospital with no recollection of why he s there what year he was born or even who he is SI Leader Ashleigh Ledet alede12 tigers lsu edu Sessions Monday 6 7 30 Allen 35 Office 39 Allen basement Wednesday 6 7 30 Allen 35 Office hours Friday 9 30 11 30 AM What type of amnesia is this retrograde memory loss from point of injury backwards losing past memory Situation 2 Patient HM http www youtube com watch v IKP6tBhM2T4 Describes anterograde Amnesia Alzheimer s is most commonly linked to this type of Amnesia memory from point of injury or trauma forward inability for form LTM Why is HM important Consolidation was impossible couldn t remember new facts He damaged his hippocampus which caused him to have anterograde type of amnesia and could no longer form explicit episodic and semantic types of memories in the hippocampus However he still showed improvements on the Tower of Hanoi task suggesting that he still had his procedural implicit memory which makes sense because he did not damage his amygdala Therefore HM is a good example of how this brain area that he damaged hippocampus is responsible for this explicit of memory and that brain area that was still working amygdala is responsible for implicit memory Infantile amnesia can t retrieve memories from before age 3 Activity 5 Describe the relationship between the brain and long term memory as well as what happens when we age Important terms to sue constructive processing memory retrieval hippocampus consolidation long term potentiation Brain and LTM Consolidation changes that take place in the structure and functioning of neurons when a memory is formed long term potentiation changes in number and sensitivity of receptor sites synapses through repeated stimulation Hippocampus area of brain responsible for the formation of LTMs LTM is a constrictive process Constructive
